In this note, we investigate the existence of periodic and asymptotically periodic solutions of a system of coupled nonlinear Volterra integro-differential equations with infinite delay. We will make use of Schauder fixed point theorem to prove our maps have fixed points.

Construction Of Some New Families Of Apostol-Type Numbers And Polynomials Via Dirichlet Character And $P$-Adic $Q$-Integrals, Yilmaz Şi̇mşek

Turkish Journal of Mathematics

In this paper, by applying the $p$-adic $q$-integrals to a family of continuous differentiable functions on the ring of $p$-adic integers, we construct new generating functions for generalized Apostol-type numbers and polynomials attached to the Dirichlet character of a finite abelian group. By using these generating functions with their functional equations, we derive various new identities and relations for these numbers and polynomials. These results are generalizations of known identities and relations including some well-known families of special numbers and polynomials such as the generalized Apostol-type Bernoulli, the Apostol-type Euler, the Frobenius-Euler numbers and polynomials, the Stirling numbers, and other …

An Efficient Technique To Solve Nonlinear Equations Usingmultiplicative Calculus, Muhammad Waseem, Muhammad Aslam Noor, Farooq Ahmed Shah, Khalida Inayat Noor

Turkish Journal of Mathematics

In this paper, we develop an efficient technique in the framework of multiplicative calculus and suggest a new class of numerical methods for solving multiplicative nonlinear equations \textit{g}(\textit{x}% ) = 1. We also develop the convergence criteria of the proposed methods. We solve the population growth model and minimization problem, which demonstrate the implementation and efficiency of the new techniques. We also show that these techniques perform much better as compared to the similar ordinary methods for solving ordinary nonlinear equations \textit{f}(\textit{x}) = 0.

Modified Objective Function Approach For Multitime Variational Problems, Anurag Jayswal, Tadeusz Antczak, Shalini Jha

Turkish Journal of Mathematics

The present paper is devoted to studying the modified objective function approach used for solving the considered multitime variational problem. In this method, a new multitime variational problem is constructed by modifying the objective function in the original considered multitime variational problem. Further, the equivalence between an optimal solution to the original multitime variational problem and its associated modified problem is established under both hypotheses of invexity and generalized invexity defined for a multitime functional. Thereafter, using the modified objective function method, we derive the saddle-point results for the considered multitime variational problem. Moreover, we provide some examples to illustrate …

Bound States And Spectral Singularities Of An Impulsive Schrödinger Equation, Emel Yildirim

Turkish Journal of Mathematics

In this paper, we study the analytical properties of the Jost function of an impulsive Schrödinger equation. We also investigate the bound states and spectral singularities of this equation. We present some conditions on the potential function that guarantee that the impulsive Schrödinger equation has a finite number of bound states and spectral singularities with finite multiplicities.

Bounded Solutions And Asymptotic Stability Of Nonlinear Second-Order Neutral Difference Equations With Quasi-Differences, Magdalena Nockowska Rosiak

Turkish Journal of Mathematics

This work is devoted to the study of the nonlinear second-order neutral difference equations with quasi-differences of the form $$ \Delta \left( r_{n} \Delta \left( x_{n}+q_{n}x_{n-\tau}\right)\right)= a_{n}f(x_{n-\sigma})+b_n $$ with respect to $(q_n)$. For $q_n\to1$, $q_n\in(0,1)$ the standard fixed point approach is insufficient to get the existence of the bounded solution, so we combine this method with an approximation technique to achieve our goal. Moreover, for $p\ge 1$ and $\sup q_n

On The Affine-Periodic Solutions Of Discrete Dynamical Systems, Hali̇s Can Koyuncuoğlu, Murat Adivar

Turkish Journal of Mathematics

Affine periodicity is a generalization of the notion of conventional periodicity and it is a symmetry property for classes of functions. This study is concerned with the existence of $(Q,T)$-affine periodic solutions of discrete dynamical systems. Sufficient conditions for the main results are proposed due to discrete exponential dichotomy and fixed point theory. Obtained results are also implemented for some economical and biological models. In particular cases, our results cover some existing results in the literature for periodic, antiperiodic, or quasiperiodic solutions of difference equations.

Effective strategies to achieve weight loss and long-term weight loss maintenance have proved to be elusive. This systematic review and meta-analysis aims to explore whether the choice of weight loss strategy is associated with greater weight loss. An electronic search was conducted using the MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online), EMBASE (Excerpta Medica database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), and PsycINFO (Database of Abstracts of Literature in the Field of Psychology, produced by the American Psychological Association and distributed on the association’s APA PsycNET) databases for clinical trials and randomized controlled …

Carcinogenesis In Prostate Cancer: The Role Of Long Non-Coding Rnas, John Aird, Anne-Marie Baird, Marvin C.J Lim, Ray Mcdermott, Stephen P. Finn, Steven G. Gray

Articles

LncRNAs appear to play a considerable role in tumourigenesis through regulating key processes in cancer cells such as proliferative signalling, replicative immortality, invasion and metastasis, evasion of growth suppressors, induction of angiogenesis and resistance to apoptosis. LncRNAs have been reported to play a role in prostate cancer, particularly in regulating the androgen receptor signalling pathway. In this review article, we summarise the role of 34 lncRNAs in prostate cancer with a particular focus on their role in the androgen receptor signalling pathway and the epithelial to mesenchymal transition pathway.

Religious Identity Formation: Constraints Imposed On Religious Institutions And Implications For The Meaning Of Religious Affiliation, Marc Von Der Ruhr, Paul Ngo, Joseph P. Daniels

Economics Faculty Research and Publications

Religiosity in the United States remains a strong social force. The United States persistently demonstrates higher religious participation than Europe. Some recent trends documented by the Pew Research Center in its 2008 and 2015 publications on the U.S. religious landscape, however, cite evidence that different religious groups are experiencing very different trends in participation. These trends show a recent and significant decline among many moderate Protestant denominations but a modest increase in participation at fundamentalist churches. The Pew Research Center similarly documents significant inconsistencies between what a religious hierarchy teaches versus what individuals personally choose to believe. For example, and …

Teachers’ Perceptions Of The Use Of Graphic Novels To Teach Reluctant Readers, Bret Ginsberg

Theses and Dissertations

The purpose of this qualitative study was to explore the perceptions of teachers in a suburban private school in Florida serving prekindergarten through Grade 8 regarding the use of graphic novels to increase student motivation to read. The problem was teachers were concerned with students’ inability to complete the required novels, demonstrate comprehension of deep meaning from the text, read silently, and read outside of school. Teachers raised serious concerns about the reading achievement of middle school students. Teachers also noted a frequent mismatch between the preference of the middle school reader and the instructional opportunities provided. The study was …

To explore ultrafast electron dynamics in materials with strong electron-electron correlation, under the influence of a laser pulse, an ab initio electronic structure method based on time-dependent density functional theory (TDDFT) in combination with dynamical mean field theory (DMFT) is developed and applied to: 1) single-band Hubbard model; 2) multi-band metal Ni; and 3) multi-band insulator MnO. The ultrafast demagnetization in Ni reveal the importance of memory and correlation effects, leading to …

The Sex/Gender Distinction In Contemporary Gender And Women's Studies Introductory Textbooks, Kyle Lighty

All Graduate Theses, Dissertations, and Other Capstone Projects

Understanding the sex/gender distinction and the social constructions of sex and gender are important learning outcomes in contemporary gender and women's studies introductory courses. These theories challenge hegemonic binary ideas about the relationships between sex and gender and between male and female identity formations. Little academic attention has been paid to how teaching materials, specifically textbooks, explore these topics, despite the potential for them to influence students and instructors. This study address this gap in the literature by using critical discourse analysis (CDA) to examine the methods being used to explore the sex/gender distinction and social constructions of sex and …

The Efficacy Of Best Management Practices On Peak Discharge And Contaminant Loads In Agricultural Drainage Systems, Blue Earth River Watershed, South-Central Minnesota, Usa, Zach Hilgendorf

All Graduate Theses, Dissertations, and Other Capstone Projects

Conversion of native land cover to row crop agriculture and anthropogenically modified hydrology, correlates with increases in peak discharge, annual discharge, sediment and nutrient loads in agricultural land-use dominated watersheds within the Mississippi River basin. This results in environmental issues related to turbidity, eutrophication-hypoxia, loss of biodiversity, natural resource degradation, reduction in tourism, and more. In no place is this more obvious than the ever-growing "Dead Zone" in the Gulf of Mexico. The Minnesota River basin, the largest tributary to the Mississippi River in Minnesota, is a disproportionately large contributor of sediment (~80-90%), nitrogen (~56%), and phosphorus (~45%) to the …

Copula Theory And Regression Analysis, Mayooran Thevaraja

All Graduate Theses, Dissertations, and Other Capstone Projects

Researchers are often interested to study in the relationships between one variable and several other variables. Regression analysis is the statistical method for investigating such relationship and it is one of the most commonly used statistical Methods in many scientific fields such as financial data analysis, medicine, biology, agriculture, economics, engineering, sociology, geology, etc. But basic form of the regression analysis, ordinary least squares is not suitable for actuarial applications because the relationships are often nonlinear and the probability distribution of the response variable may be non-Gaussian distribution. One of the method that has been successful in overcoming these challenges …

Comparative Study Of Cv3 Carbonaceous Chondrites Allende And Bali Using Micro-Raman Spectroscopy And Sem/Eds, Raka Paul

All Graduate Theses, Dissertations, and Other Capstone Projects

The birth of the solar system (over 4 billion years) is speculated to have happened from a nebula, swirling and compacting in localized regions to eventually form the Sun and planets. This complex process consists of numerous changes and intermediary steps, yet to be fully understood. Carbonaceous chondritic meteorites are relics of that process and therefore have potential to reveal information about the formation history. Several theories have been formulated linking their composition to planet formation. This study focusses on two carbonaceous chondritic specimens, Allende and Bali, both of the group CV and petrologic type 3. CV meteorites are abundant …

Preventing Osteoarthritis By Targeting The Transforming Growth Factor Beta Signaling Pathway, Robert Dalton Chavez

All ETDs from UAB

Osteoarthritis (OA) is characterized by degenerated cartilage. In age-related OA, the molecular mechanisms that initiate cartilage erosion are not well defined. However, transforming growth factor beta (TGF-β) signaling is attenuated in the cartilage of patients with age-related OA and therefore may play a role in the disease. Degenerated cartilage has a rough surface and exhibits changes in stiffness. Proteoglycan 4 (PRG4), also known as lubricin, helps lubricate the surface of cartilage, and 3’-phosphoadenosine 5’-phosphosulfate synthase 2 (PAPSS2) helps maintain the stiffness of cartilage. Both PRG4 and PAPSS2 are regulated by TGF-β and down-regulated in OA cartilage. The present research elucidated …

Annual Climate Impacts On Tree Growth And Post-Fire Regeneration In Ponderosa Pine And Douglas-Fir In The Northern Rocky Mountains, Lacey Hankin

Graduate Student Theses, Dissertations, & Professional Papers

Widespread changes in climate and disturbance regimes, including prolonged drought and increases in the size and frequency of wildfires, have raised concerns regarding forest resilience to environmental change. Dry mixed-conifer forests have persisted for centuries under mixed-severity fire regimes; however, climatically driven increases in the frequency of large wildfires in recent decades may lead to increased tree mortality and declines in post-fire tree regeneration. Climatic warming and increased drought may also impact tree growth, with implications for the carbon cycle. Lower-treeline forests near the edge of their climatic tolerance may be particularly vulnerable to these impacts of future climate warming …

Elucidaton Of The Pysical And Chemical Properties Of Cytochrome C – Cardiolipin Interactions, Margaret Marie Elmer-Dixon

Graduate Student Theses, Dissertations, & Professional Papers

Recently, the electron transport protein Cytochrome c (Cytc) was shown to interact with the mitochondrial lipid cardiolipin (CL) during the initial stages of the intrinsic apoptotic pathway. This interaction is characterized by the protein binding and oxidation of cardiolipin on the concave surface of the outer leaflet of the inner mitochondrial membrane. To date, this interaction has been studied with a variety of methods and techniques reporting varied and often conflicting findings characterizing the nature and extent of the protein-lipid interaction. Cytc has been hypothesized to interact with cardiolipin electrostatically, hydrophobically and through hydrogen bonding and is thought to partially …

Photochemical Cycling Of Reactive Oxygen Species In Hydrothermal Systems: Impacts On Biosignature Preservation, Megan A. Mave

Graduate Student Theses, Dissertations, & Professional Papers

Life originated on early Earth, despite harsh, highly reducing conditions. Life may have also emerged on early Mars, when conditions on the two planets were similar (i.e. before atmosphere loss and desiccation). NASA’s 2020 Mars rover mission aims to identify biosignatures (i.e. evidence of life) in early Martian deposits. Potential exploration sites include extinct hydrothermal springs, due to their high habitability and preservation potential. This study aims to better understand biosignature preservation in hydrothermal systems analogous to those on early Mars (i.e. reducing and Fe-rich).

Reactive oxygen species (ROS) are highly reactive molecules formed primarily by photochemical reactions. ROS are …
